Dark Dull Bones
From the Super Mario Wiki, the Mario encyclopedia
Dark Dull Bones are Dull Bones in the game Super Paper Mario that look like a shadow. Dark Dull Bones appear in rooms 16, 19 and 24 of the Flopside Pit of 100 Trials. Just like the many dark versions of enemies in the game, they are stronger than Dull Bones, though both enemies share the same attack pattern, which consists in throwing bones at Mario and co. They are very weak against Bowser's Fire Breath.
